Actual amount of input

While calculating profit-linked productivity change, the amount of input i that would have been used for the current period in the absence of a productivity change is determined by: a. dividing the current-period output by the base-period productivity ratio for input i. O b. dividing the price-recovery component by the base-period productivity ratio for input i. c. deducting the total profit change from the current-period output. O d. deducting the total profit change from the actual amount of input i used in the current period.
